The Dia-Braze™ features a single reflection diamond optical element which is brazed into tungsten carbide as its sampling stage. The anvil that compresses the sample onto the sampling stage is sapphire. This combination of extremely hard and durable materials enables application of extremely high pressures on the sample using the bridge style pressure applicator, which has a built in pressure control mechanism. By enhancing contact between the optic and the diamond optical sampling stage, optimum optical contact is assured.
Once optimum optical contact has been achieved, no increase in absorbance intensity is possible and maximum sensitivity is achieved. By assuring optimum contact, the Dia-Braze™ enables control over reproducibility of results from sample to sample.
The Dia-Braze™ is available with several very useful options. There are seven anvil options (see product description below) which include the standard sapphire anvil, volatiles cover, view through, flow through, pellet anvil, reactive anvil, flat anvil, and 2 grooved anvils. A germanium top plate is available for very strongly absorbing samples. An optional heated top plate with diamond optics can heat samples to 200°C. A reaction vessel for pressures up to 3000 psi at 200°C is available for flow through and static sampling. A wire holder top plate set with two (2) grooved anvils is available for the study of coated wires. A specular reflection top plate is available for micro reflectance samples, very highly absorbing samples and carbon black containing polymers.
